1. Protein Surfaces Probed by Aqueous Two-phase Partitioning
Sammanfattning : This thesis is concerned primarily with peptide and protein partitioning in aqueous two-phase systems and the connection between partitioning behavior and protein structure. The surface properties of a protein is often crucial for recognition and interaction with other molecules. LÄS MER
2. Methodologies to assess the fate of polar organic compounds in aquatic environments
Sammanfattning : Polar organic compounds (POCs) are chemicals with polar functional groups in their structure. The functional groups make the compounds hydrophilic and less prone to partition with biota. However, the knowledge of their fate is limited due to difficulties associated with their measurements.

3. Metal Speciation and Toxicity in Sewage Sludge
Sammanfattning : Increasingly stringent controls on metal concentrations in sewage sludge destined for agricultural application provided a basis for the study of the relevance of metal speciation in sewage sludge. A comprehensive literature review identified difficulties in relating metal speciation through single chemical extractions to plant uptake and soil toxicity. LÄS MER
4. Peptide-tagged proteins in aqueous two-phase systems
Sammanfattning : This thesis deals with proteins containing peptide tags for improved partitioning in aqueous two-phase systems. Qualitatively the peptide-tagged protein partitioning could be predicted from peptide data, i.e. partitioning trends found for peptides were also found for the peptide-tagged proteins. LÄS MER
5. Analytical Aspects of Atmospheric Pressure Ionisation in Mass Spectrometry
Sammanfattning : The actual signal recorded with an analytical instrument is not always a true reflection of the analysed sample. In this thesis a further insight of the atmospheric pressure ionisation processes electrospray (ESI) and atmospheric pressure chemical ionisation (APCI) has been endeavoured, to provide a deeper understanding of and ways to minimize this bias.
